Benefits of technology

The design improves electromagnetic wave shielding efficiency by decreasing electrical resistance, thereby preventing communication issues and malfunctions caused by electromagnetic interference.

Problems solved by technology

Generally, the above-mentioned camera module generates electromagnetic waves while being driven, and when such electromagnetic waves are discharged externally, other electronic components may be negatively influenced, to thereby cause communications problems or malfunctions.
However, when using the conductive bond, electrical resistance for shielding electromagnetic waves may be increased, whereby efficiency in shielding electromagnetic waves may be decreased.
